In-depth understanding of how LED chips work The magic of LED chips comes from the wonderful properties of semiconductor materials. When an electric current passes through the P-N junction between the P-type semiconductor and the N-type semiconductor, the electrons recombine with the holes, releasing energy that is converted into visible light.
Principle: A chip is an integrated circuit, consisting of a large number of transistors. Different chips have different integration scales, up to several hundred million; As small as a few hundred transistors. Transistors have two states, on and off, denoted by 0Tooth chips, Wi-Fi chips, etc., are used to receive and send wireless signals to achieve wireless communication and data transmission.
2, the chip is the integrated circuit. An integrated circuit is a tiny electronic device or component.
3, the role of the chip: common chips are: CPU, GPU, memory flash, memory card DRAM, microcontroller MCU, digital-to-analog conversion chip, analog-to-digital conversion chip, sensor chip: such as temperature sensor, humidity sensor, etc., LED light chip and so on.
4, the main role of the chip is to complete a variety of electronic functions in a tiny space, such as amplifying signals, switching, storing data, performing logical operations, etc. It is a core component of modern electronic equipment and is widely used in a variety of fields, including computers, communications, medical equipment, automobiles, home appliances, etc.
5, the role of the chip is to control any port of the electronic device. The chip appears to the naked eye as a square object with many "electronic feet." In fact, it is its various integrated circuits, chips used in different devices have different functions, there are control baseband, control voltage conversion and so on.
The working principle of the chip is: the circuit is manufactured on the surface of the semiconductor chip for calculation and processing. Integrated circuits have two main advantages over discrete transistors: cost and performance.
"The working principle of the chip is to manufacture the circuit on the surface of the semiconductor chip for calculation and processing. Transistors have two states, on and off, represented by 1 and 0 respectively, and multiple transistors can produce multiple 1 and 0 signals, which are programmed for specific functions to process these letters and graphics.
The IC555 chip works on the principle that the output voltage of the two comparators controls the state of the RS trigger and the discharge tube. A voltage is added between the power supply and the ground, and when pin 5 is suspended, the voltage at the in-phase input of the voltage comparator C1 is 2VCC /3, and the voltage at the invert input of C2 is VCC /3.
shapeThe resulting integrated circuit is placed on a plastic base to make a chip. Almost all chips seen today can be called IC chips. An integrated circuit is a tiny electronic device or component.
1, the car key chip was invented by Rubik's Cube Technology, and its core principle is the use of radio frequency identification technology. The technology stores the vehicle's identity information in a microchip, which is controlled by a smart key. Initially limited to luxury car brandsFor example, BMW and Mercedes, cost reduction has now spread to all brands.
2, in the car key, we see that the car key chip is not exposed, is made of plastic and rubber key shape, that is because the car key anti-theft chip is a passive magnetic coupling forwarding system, only through the electromagnetic wave range of 125 kHz frequency.
3, actually is RFID. In fact, it is a non-contact swipe card system (there is also a contact type is not discussed here), it is a radio frequency system, the electricity on the chip is obtained by radio frequency induction, and the microwave induction principle is used at high frequency.
